A painter weighing 180 lb working from a "bosun's" chair hung down the side of a
tall building, desires to move in a hurry. He pulls down on the fall rope with
such a force that he presses against the chair with only a force of 100 lb. The
chair itself weighs 30.0 lb.

(a)What is the acceleration of the painter and the chair?

(b)What is the total force supported by the pulley?
